Definitions

  • the present invention pertains to systems for treating conditions, such as sleep disordered breathing, using positive airway pressure (PAP) therapy, and, in particular, to an inline adapter for a pressure support device that also allows for an electrical connection to be made between electrical (e.g., heated tubing) and the pressure support device.
  • PAP positive airway pressure
  • CPAP continuous positive airway pressure
  • variable airway pressure wherein the pressure provided to the airway of the patient is varied with the patient's respiratory cycle.
  • Such therapies are typically provided to the patient at night while the patient is sleeping.
  • Non-invasive ventilation and pressure support therapies involve the placement of a patient interface device including a mask component having a soft, flexible sealing cushion on the face of the patient.
  • the mask component may be, without limitation, a nasal mask that covers the patient's nose, a nasal/oral mask that covers the patient's nose and mouth, or a full face mask that covers the patient's face.
  • Such patient interface devices may also employ other patient contacting components, such as forehead supports, cheek pads and chin pads.
  • the patient interface device is connected to a gas delivery tube or conduit and interfaces the ventilator or pressure support device with the airway of the patient, so that a flow of breathing gas can be delivered from the pressure/flow generating device to the airway of the patient. It is known to maintain such devices on the face of a wearer by a headgear having one or more straps adapted to fit over/around the patient's head.
  • Some patients that use non-invasive ventilation and/or pressure support therapy devices have a need to add an inline accessory to the flow path of the device.
  • Such accessories may include, for example and without limitation, oxygen enrichment adapters, pressure valves and bacteria filters.
  • many patients are now using heated tubes in the flow path. Such heated tubes require an electrical connection to be made between a connector on the tube cuff and a connector near/on the outlet port of the ventilator or pressure support device. The requirement for such an electrical connection, however, makes it difficult to also use an inline accessory.
  • the oxygen in order to maintain heated tubing functionality while simultaneously receiving supplemental oxygen, the oxygen must be introduced to the patient at the mask side of the patient circuit, either directly into the mask or into an enrichment adapter provided between the mask and the main delivery conduit. This adds bulk to the mask and/or forces the patient to have additional tubing running to their face. This can reduce the comfort of the therapy experience, and thus may lease to decreased therapy compliance.
  • WO 2008/076230 A2 discloses an adapter apparatus for a respiratory therapy system.
  • a respiratory system comprising a flow generator, a humidifier system for heating and humidifying a breathable gas received from the flow generator, and a conduit for supplying a breathable gas from the humidifier system to a patient interface.
  • the flow generator may also be a CPAP unit with an integrated humidifier and heating system. The amount of heating is under control of a controller.
  • This document also dsicloses a controller applied in a modular respiratory system, which is directly connected with one end to the flow generator, and with another end to a conduit cuff which is connected to a conduit, the conduit being connected to a further cuff with the aid of a connection cuff, the further cuff being connected to a human machine interface.
  • This document also discloses two interconnecting conduits being removably connectable to each other, each of the interconnecting conduits comprising a male fitting which is removably connectable to a female fitting of another interconnecting conduit.
  • the interconnecting conduits may contain electrical wires, provided for heating or communication purposes.
  • the interconnecting conduit sections may contain male and female fittings at either end, provided to allow electrical connection to additional conduits.
  • the male and female fittings can connect to controllers used for the purpose of controlling, to flow generators, humidifiers and any other associated equipment.
  • the fittings of the interconnecting conduit can connect to cuffs. This has the advantage of isolating the cuff from the hose structure.
  • the interconnection conduits wiring for the heating/information transfer can be located within the hose structure, and this hose structure can be helically wound, extrusion blowmoulded or extrusion pipe.
  • the wires can also be located down the middle of the respiratory conduit.
  • the wires may be located externally of the respiratory conduit.
  • an enrichment adapter apparatus according to claim 1 and a respiratory therapy system according to claim 6.
  • the dependent claims 2-5 and 7-10 define preferred embodiments of the invention.
  • the word "unitary” means a component is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a “unitary” component or body.
  • the statement that two or more parts or components "engage” one another shall mean that the parts exert a force against one another either directly or through one or more intermediate parts or components.
  • the term “number” shall mean one or an integer greater than one (i.e., a plurality).
  • System 2 adapted to provide a regimen of respiratory therapy to a patient according to a non-claimed example is generally shown in FIG. 1 .
  • System 2 includes a pressure generating device 4, a delivery conduit assembly 6 (described in detail herein), and a patient interface device 8 including an elbow conduit 10 fluidly coupled to delivery conduit assembly 6.
  • Pressure generating device 4 is structured to generate a flow of breathing gas and may include, without limitation, ventilators, constant pressure support devices (such as a continuous positive airway pressure device, or CPAP device), variable pressure devices (e.g., BiPAP®, Bi-Flex®, or C-FlexTM devices manufactured and distributed by Philips Respironics of Murrysville, Pennsylvania), and auto-titration pressure support devices.
  • Delivery conduit assembly 6 is structured to communicate the flow of breathing gas from pressure generating device 4 to patient interface device 8.
  • delivery conduit assembly 6 is a heated delivery assembly that also allows for inclusion of an inline accessory 7 (such as, without limitation, an oxygen enrichment adapter, a pressure valve, a bacteria filter, or any other suitable accessory device that may be used in the patient circuit of a respiratory therapy device), shown schematically in FIG. 1 , in the flow path from pressure generating device 4 to patient interface device 8.
  • an inline accessory 7 such as, without limitation, an oxygen enrichment adapter, a pressure valve, a bacteria filter, or any other suitable accessory device that may be used in the patient circuit of a respiratory therapy device
  • patient interface 8 is a nasal/oral mask structured to cover the nose and mouth of the patient.
  • any type of patient interface device 8 such as, without limitation, a nasal mask that covers the patient's nose, a nasal cushion having nasal prongs that are received within the patient's nares, or a full face mask that covers the patient's face, which facilitates the delivery of the flow of breathing gas to, and the removal of a flow of exhalation gas from, the airway of a patient may be used.
  • patient interface 8 includes a flexible cushion 16, a rigid or semi-rigid shell 18, and a forehead support 20.
  • Straps (not shown) of a headgear component may be attached to shell 18 and forehead support 20 to secure patient interface device 8 to the patient's head.
  • An opening in shell 18 to which elbow conduit 10 is coupled allows the flow of breathing gas from pressure generating device 4 to be communicated to an interior space defined by shell 18 and cushion 16, and then, to the airway of a patient.
  • the opening in shell 18 also allows the flow of exhalation gas (from the airway of such a patient) to be communicated to an exhaust assembly 12 provided on elbow conduit 10.
